How do the colonies appear on media, for example specifically, on blood agar and Phenylethyl alcohol (PEA)?

I understand that it's alpha hemolytic on blood agar and shows greenish color around the colonies. But what I don't get and would like to make sure is how do the colonies look like on it?? For example, should the colonies be tiny, circular, convex, irregular, what color if any....??

Does this sound accurate for Strep pneumoniae. This is what I got for my PEA agar:-colony morphology for PEA= tiny,pinpoint,circular/convex, irregular, and smooth colonies on the PEA.

I've already done the gram stain and got a gram positive stain. I get that but I just want to make sure how I can write the morphology of the colonies and how they should look, in case I am wrong with this.
